Asked whether she was a feminist by The Daily Beast in 2012, she said: "I don't really think about things as guys versus girls. I was... brought up to think if you work as hard as guys, you can go far in life."

"I didn't have an accurate definition of feminism when I was younger," she told Maxim of her earlier comments. "I didn't quite see all the ways that feminism is vital to growing up in the world we live in. I think that when I used to say, 'Oh, feminism's not really on my radar,' it was because when I was just seen as a kid, I wasn't as threatening."

In slightly less campaigning feminist news, Swift has just released her cameo-studded new music video for single "Bad Blood", which features Victoria's Secret models and, erm, Lena Dunham, wielding compact mirrors as weapons and kicking their opponents in the face with stiletto shoes.

The song is thought to be about a fall-out she had with former friend Katy Perry, though Swift is yet to confirm the speculation.
